How to maintain the worm gear butterfly valve?

How to maintain the worm gear butterfly valve? After the worm gear butterfly valve is installed and put into operation, attention should be paid to the maintenance of the worm gear butterfly valve. Only by doing a good job of daily maintenance can we ensure that the worm gear butterfly valve can maintain normal and stable operation for a long time, and our production work will not be affected. Shanghai Huquan valve provides you with some suggestions on the maintenance of worm gear butterfly valve:

1. The idle butterfly valve shall be stored in a dry, ventilated and cool place, and both ends of the valve passage shall be blocked to prevent dust and impurities.

2. Check the butterfly valve regularly, apply anti rust oil on the external surface of the valve, and clean the dirt on the valve body in time.

3. The butterfly valve after installation needs regular maintenance to ensure its normal and stable operation. The parts requiring maintenance include:

① Whether the sealing surface of the butterfly valve is worn. If it is worn, it shall be repaired or replaced in time.

② Check whether the trapezoidal thread of the valve stem and valve stem nut is seriously worn and whether the packing is outdated and invalid. If any problem is found, replace it in time.

③ Regularly check the tightness of the butterfly valve and deal with the leakage in time.

④ The whole valve shall be intact, including the bolts on the flange and support, to ensure that the threads are not damaged or loose.

4. If the external environment of the worm gear butterfly valve is relatively bad and is easy to be affected by bad weather, the valve shall be equipped with a protective cover.

5. Keep the scale on the butterfly valve complete, accurate and clear.

6. Do not strike the valve working in the pipeline, and do not support heavy objects.

The normal operation of the worm gear butterfly valve is related to the smooth progress of the project, so we must pay attention to the maintenance of the worm gear butterfly valve.
